Detailsinfo

A vulnerability was found in OSSP mm Library up to 1.1.x (Software Library). It has been rated as critical. Affected by this issue is an unknown part of the component Apache User Handler. The manipulation with an unknown input leads to a symlink vulnerability. Using CWE to declare the problem leads to CWE-61. The product, when opening a file or directory, does not sufficiently account for when the file is a symbolic link that resolves to a target outside of the intended control sphere. This could allow an attacker to cause the product to operate on unauthorized files. Impacted is confidentiality, integrity, and availability. CVE summarizes:

OSSP mm library (libmm) before 1.2.0 allows the local Apache user to gain privileges via temporary files, possibly via a symbolic link attack.
